Specification of Letters Patent.

Patented Feb. 2, 1909.

To whom it may concern:

Be it known that I, BENJAMIN L. BRAD- LEY, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented a new and useful Improve ment in Varnishing Machines, of which the following is a specification.

My invention relates to improvements in molding varnishing machines.

The object of my invention is to provide a machine of the character described in which the molding is fed continuously through the machine in an inverted position and the varnish applied to thelower face thereof evenly and as itpasses from the machine the surplus varnish is rubbed therefrom to give to the molding an even smooth finish,

I also provide a machine with which moldings of different widths and thicknesses can be readily varnished.

Another object of my invention is to provide a more simple cheap and eifective machine of this character as will be hereinafter fully described.

In the accompanying drawings, Figure 1, is a side elevation of my improved machine. Fig. 2, is a top plan. Fig. 3, is an end view looking from the end of the machine in which the molding is fed as indicated by the arrow Fig. 1. Fig. 4, is an enlarged vertical sectional view of the varnish containing receptacle showing the rotary brush in side elevation. Fig. 5, is, a vertical sectional view of the varnish containing tank and from which the varnish is fed to the receptacle.

Referring now to the drawings, 1, repre sents a rectangular frame composed of vertical standards or legs 2 and 3, on each side and connected together by the transverse bars 4 and 5 at each end and the standards at their upper ends are also'conneoted together by the longitudinal horizontal bars 6 and 7 and below the same by bars 8 all of which form the rectangular. frame 1 for supporting the numerous parts of the machine.

Carried by the upper horizontal beam 6 of the frame are two outwardly extending brackets 9 and 10, which extend a considerable distance outwardly, and are provided withvertical elongated slots 11, extending longitudinally thereof. These brackets form the support and guide for the molding as it is being fed through the machine. Resting upon these brackets arelongitudinally extending guide rails 12 and 13, through which whereby Said bolts extending through the slots 11 and whereby the guide rails may be adjusted transverse of the machine, or to and from each other to receive moldings, of difierent widths. The outer rail 13 is provided with an upwardly extending flange 14 which extends ,sufliciently high to go beyond the rounded enlarged portion of the molding it serves as an accurate guide for the molding.

The lower faces of the beams 6 and 7 are pro- Vided with journals in which is mounted a transverse shaft 15 which on the outside of the frame is provided with a large drive pulley 16 by means of which the shaft is rotated. At the feed end of the frame the standards 2 are providedwith journals 17 in which is mounted a shaft 18, and the said shaft intermediate the standards is provided with the pulleys 19 and 20 over which the belt 21 passes. Said belt is driven by any desired motor andby means of which the entire machine is driven. The shaft 18 extends beyond the frame and has keyed thereon a small pulley 22 and a larger pulley 23. The pulley 22 is in alinement with the pulley 16. Passing around said pulleys is a belt 24 by means of which the shaft 15 is slowly rotated owing to the relative sizes of the two pulleys.

The shaft 15 intermediate the beams 6 and 7 is rovided with a small gear wheel 25 mounte on the lower face of the beams 6 and 7. On opposite sides of the shaft 18 are shafts 26 and 27 which have gears 28 and 29 carried thereby and which mesh with the gear 25 and said gears being larger than the gear 25 the shafts 26 and 27 are caused to'rotate slowly in the same direction. The shafts 26 and 27 extend out beyond the side of the frame and are provided with feed rollers 30 and 31, which are of a width and diameter to extend upwardly between theguide rails 12 and 13 and engage the molding 32, and whereby the same is fed longitudinally through the machine.

The beams 6 and 7 are provided with two upwardly extending sets of brackets 33 and ried by said bar is a roller carrying frame 38. 1 'l. he said frame is composed of the horizontal 1 arms 39, in which is mounted the friction roller 40, which is adapted to engage the upper face of the molding, directly above the feed roller 31. and firmly holds it thereon so that it will be properly fed forward.

The vertical portion 4] of the roller carry ing frame is provided with a vertical slot 42 and passing through the slot 37 in the bar 35 and the slot 42, is a clamping bolt 43, which firmly clamps the said frame in its adjusted position. By the arrangement of the two slots it will be seen that the roller can be adjusted vertically when using molding of different thicknesses and can be adjusted in or out so as to centrally engage the said molding.

The wheel 40 is preferably shown grooved to correspond to that of the back of the molding so as to more firmly hold the molding in its downward position upon the feed roll.

The brackets 33 carry a bar 44, which carries a wheel frame 45. Said frame carries the wheel 46 which is directly above the wheel 31 and is mounted the same as the frame 41 to have a vertical and horizontal movement, all of which has been fully described in respect to the frame 41.

'lhe standards 3 on the inside are provided with a bearing in w hich is mounted a shaft 47 vi hich extends beyond the frame at both ends. At one end said shaft is provided u ith a pulley 48 w hich is in a line v. ith the pulley 23.- A belt 49 asses around said pulley by means of w hich the shaft 47 is rotated. The said shaft on the opposite side of the frame is provided with a u heel like member composed of a hub 50, having a series of spokes 51, which carry at their outer ends brush clamping members 52, which are adapted to clamp and hold the varnish brushes for applying the same to the under side of the molding. The said clamping members are formed by transverse bars 53 carried by the spokes and provided with bolts 54,- which pass through bars or plates 55, corresponding with the bars 53 and by means of the bolts the ordinary paint brush 56 may be readily clamped and whereby brushes of different widthsmay be used when varnishing moldings of different widths. The said brushes are so arranged that their upper ends or bristles extend slightly above a plane with the upper face of the brackets, and whereby the varnish is applied to the lower face of the molding.

The horizontal bar 8, directly below the brush member is provided with the varnish containing receptacle 57, which by means of the bracket 58 is vertically adjustable. The said tank is of an elongated form and so positioned that the brush carrying arms pass within the same adjacent to the lower end and from this receptacle the brushes are fed with thevarnish. The receptacle 57 adjacent one corner, is provided with a transverse bar 59, which carries a scraper 60, u hich is adjustably held by a set screw 61, whereby it is adjusted up and down. This scraper is in the path of rotation of the brushes and is adapted to scrape the surplus varnish from the brushes, to prevent too much being applied to the molding. The amount of varnish is regulated by the adjustment of the scraper. I have shown two other scrapers 62 and 63, which can he used to more thoroughly accomplish the result of limiting the amount of varnish applied. The frame 1, also carries a spreader 64, v. hich is in the path of rotation of the brushes. The bristles thereof engage the spreader and evenly spread the varnish on the brushes so that the varnish u ill be evenly spread upon the molding. l. 1e varnish is supplied to the receptacle 57 from a tank 65, supported upon a bracket 66, carried by the upper face of the frame. A pipe 67 leads dounwardly from the lower end of the tank to the receptacle, and the said pipe below the tank is provided with a cock 68 for cutting oil the supply of varnish to the receptacle.

In order to keep a determined amount of varnish in the receptacle, and to automatically feed the oil thereto, as it is used by the brushes, 1 make the tank perfectly air tight and connect to the upper end thereof a pipe 69, which leads downwardly and is connected to the side of the receptacle as indicated at 70. The said connection 70 is at a point at which the desired amount of varnish is desired in the receptacle. As the varnish is used the connection 70 is opened so that air passes into the pipe 69 and to the tank 65, and allows the varnish to flow to the receptacle through the pipe 67 and when the varnish has risen in the receptacle to close the connection 70, the air is shut oil from the tank and the flow of varnish is stopped.

Secured to the beams 6 and 7 are brackets 71, which have bolted thereto the transverse bar 72 similar to the bars 44 and 35, and has an elongated slot in its end beyond the frame. The said bar carries a keeper 73, which is secured thereto by means of a bolt 74, and said keeper bears upon the upper face of the molding and holds the molding firmly down upon the brushes so that the varnish will be applied to all parts thereof. The beams 6 and 7, are provided with brackets 75, adjacent the ends opposite the feed end and carrying a bar 76, which is provided with a slot and a wheel carriage 77, vertically and horizontally adjustable the same as the carriages 45 and. 41 heretofore described. rhe said carriages have a wheel 78 bearing upon the upper face of the molding whereby the molding is firmly hold down upon the rubber which is supported by the frame. Said ru ber may be of any desired material and its upper face is formed of a curvature to correspond with the molding and the rubber is adapted to remove all surplus varnish therefrom and give afinishto the molding.

'The molding, as before stated, is fed to the machine from the right as shown by arrow, Fig. 1. It is'first placed upon the bracket 9 between the guide rails 12 and 13 andis pushed forward and engaged. by the roller 40, which holds it down u on the feed roller whereby the molding is ed forward to the second feed roller 31 and the roller 46 and is continued to be fed forward The molding is. next engaged by the presser 73 which holds it down upon rotary brush-whereby the varnish is applied to the molding. The molding is next engaged by the roller 78 which holds the molding down upon the rubber 79 and the molding comes from the machine completed. Moldings of this character as well understood, are in pieces of considerable length and these pieces are fed in a continuous line through the machine.
